console: minor console refactoring by BridgeAR · Pull Request #17707 · nodejs/node

BridgeAR · 2017-12-16T07:26:36Z

Some minor changes

console: make error handling engine agnostic

Calling write could throw a maximum call stack size error. To make
sure this is not specific to a single engine (version), lazily
populate the correct error message by producing such a error on
demand.

console: make variables and checks stricter

console: use spread instead of apply

The performance seems pretty similar to the any other method and
this is the most readable one.
Also fix and refactor the console benchmark. It did not test console
so it got renamed and mainly tests the different ways of passing
arguments through

console: order functions and remove \n\n

This lists all function aliases directly below the declared function.

doc: remove old console note

This should not be important anymore in newer docs. The change is
also documented in the "changed" part of the function.

Checklist

make -j4 test (UNIX), or vcbuild test (Windows) passes
tests and/or benchmarks are included
documentation is changed or added
commit message follows commit guidelines

lib/console.js

Using Boolean(ignoreErrors) might be more readable here.

lib/console.js

The spread operator, unlike .apply(), pushes the elements onto the stack. That is, it makes stack overflows more likely.

Comments addressed. I removed the spread operator again and added a comment about it.

+const nullStream = createNullStream();


Unrelated but can't this be simplified to just new Writable({ write: () => {} })?

I went ahead and removed the fake console overall as it had no real purpose in this benchmark.

should this be backported to v6.x or v8.x?
